Last but not least, Mad Men actor Ben Feldman married his girlfriend Michelle Mulitz on Saturday at the Smokey Farm in Glen Farm in Gaithersburg, Maryland. "Michelle and I were so excited to share this beautiful day with our best friends and family in DC," Feldman said. "And no amount of thunderstorms, police chases, government shut downs or self-immolations could keep us from having the best party of our lives." Feldman and Mulitz were feted by 350 guests, some of which were Wolf Blitzer and his wife Lynn Greenfield, Veep star Reid Scott and Tony Award winner Patina Miller. The pair, who got engaged in December 2012, married in a barn, after which guests were escorted into a separate pavilion for dinner and dancing.
